I have a 1991 Civic STD with the stock D15B1 but it smokes and the guy I bought it from took some on the parts off the DPFI. I was going to MPFI swap it and maybe rebuild it. But decided to buy a 95 Civic and swap the motor. When I got the 95 home I found out it had already been swapped and has a D16Y7 that was running on a P28 ecu. Seeing as how I was already going to be doing the MPFI/OBD1 conversion and now have a P28 I was tossing around the idea of making a mini me out of the parts I have and a D16Y8 head. Would it work?

Parts I have
D16Y7 Block
Unknown internals
D16Y7 Head
D15B7 IM (already on Y7)
P28 ECU
Unknown 5 speed from the 95
4 speed from the 91
OBD0-OBD1 ecu and dizzy harnesses
Unknown OBD1 Dizzy
